Description

Technical Field

[0001] This utility model relates to the field of metal corrugated pipe production technology, and in particular to a device for cleaning the inner wall grooves of metal corrugated pipes. Background Technology

[0002] Metal corrugated pipes are pipes with a regular wavy shape. Commonly used metal corrugated pipes include those made of carbon steel and stainless steel, as well as steel-lined plastic, aluminum, and others. They are mainly used for non-concentric axial transmission requiring a very small bending radius, irregular bends, expansion and contraction, or absorbing thermal deformation of pipelines, or for connecting pipes to other pipes or connecting pipes to equipment in situations where it is inconvenient to install them with fixed elbows. Because of the wavy shape of the metal corrugated pipe, some difficult-to-clean stains may remain on the grooves of the inner wall, and some of these stains can corrode the inner wall of the metal corrugated pipe.

[0003] When cleaning metal bellows, the commonly used cleaning equipment usually places the metal bellows horizontally before cleaning. This can easily leave impurities and other residues on the metal bellows, requiring the metal bellows to be manually stood upright to remove water stains. This can easily cause workers to accidentally get too much water on themselves, affecting their work. In addition, the limitations imposed on the metal bellows also present many inconveniences. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for cleaning the inner wall grooves of metal bellows, thereby solving the problems mentioned in the background art.

[0005] A device for cleaning the inner wall grooves of a metal bellows includes a base and a cleaning mechanism and a limiting mechanism mounted on the base. The cleaning mechanism includes an electric push rod, a drive rod, a gear ring, a gear, a motor, and a cleaning brush. The gear ring is rotatably mounted on the upper end plate of a bracket one of the base. The gear is mounted on the output end of the motor and is connected to the gear ring in a transmission manner. The electric push rod is mounted on the upper end plate of a bracket two on the bracket one. The drive rod movably passes through the gear ring, and its top is rotatably connected to the output end of the electric push rod. The cleaning brush is detachably fixed to the bottom of the drive rod.

[0006] The limiting mechanism includes a bracket three, an adjusting plate one, a limiting head, a limiting seat, a slide, an adjusting plate two, a screw, a nut, and a movable seat. The movable seat is slidably mounted on the base and limited by a limiting pin. The limiting seat is fixed to the movable seat. Multiple adjusting plates two are provided, and the sliding plate slides along a groove of the limiting seat. The screw is fixed to the bottom of the slide and inserted into the groove two of the movable seat. The nut is rotatably mounted on the screw to limit the screw's downward movement. The bracket three is fixed to the edge of the limiting seat. Multiple adjusting plates one are provided, penetrating the upper end of the bracket three and limited by a locking pin that rotates on the bracket three.

[0007] By adopting the above technical solution, it is convenient to limit and clean the metal bellows.

[0008] A convex key is provided on one side of the outer wall of the drive rod, and a concave key is provided on the inner wall of the toothed ring. The outer wall contour of the drive rod is adapted to the inner wall contour of the toothed ring.

[0009] By adopting the above technical solution, it is possible to facilitate the up-and-down movement and rotation of the drive rod.

[0010] The limiting head is designed with an arc shape, with a protrusion on one end face and a groove on the other end face. An adjusting plate is inserted into the groove, and a fixing post is also provided in the groove, penetrating the adjusting plate. The thickness of the adjusting plate is less than the width of the groove, so that the position of the limiting head can be adjusted up and down along the adjusting plate.

[0011] By adopting the above technical solution, the metal bellows is defined.

[0012] The limiting seat is a hollow, inverted frustum-shaped structure with openings at both ends.

[0013] By adopting the above technical solution, it is possible to define the bottom of the metal bellows.

[0014] The base is also fitted with a limiting pin to restrict the movement of the limiting seat.

[0015] By adopting the above technical solution, the base is prevented from moving during the cleaning of the metal bellows.

[0016] The beneficial effects of this utility model for cleaning the inner wall grooves of metal bellows are:

[0017] This device uses a vertically placed metal bellows, which can directly flush out debris and impurities during cleaning. The bottom of the metal bellows is not affected by the device's components, thus avoiding incomplete cleaning and the problem of water not draining easily from the bottom of the metal bellows. Furthermore, the device provides stable confinement to the metal bellows, making cleaning more convenient. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-2 A device for cleaning the inner wall groove of a metal bellows includes a base 1 and a cleaning mechanism and a limiting mechanism mounted on the base 1. The cleaning mechanism includes an electric push rod 2, a drive rod 3, a gear ring 4, a gear 5, a motor 6, and a cleaning brush 7. The gear ring 4 is rotatably mounted on the upper end plate of the bracket 101 of the base 1. The gear 5 is mounted on the output end of the motor 6 and is connected to the gear ring 4 in a transmission manner. The electric push rod 2 is mounted on the upper end plate of the bracket 2 102 on the bracket 101. The drive rod 3 movably passes through the gear ring 4, and its top is rotatably connected to the output end of the electric push rod 2. The cleaning brush 7 is detachably fixed to the bottom of the drive rod 3.

[0023] The limiting mechanism includes a bracket 3 8, an adjusting plate 1 9, a limiting head 10, a limiting seat 11, a slide 12, an adjusting plate 2 13, a screw 14, a nut 15, and a movable seat 16. The movable seat 16 is slidably mounted on the base 1 and limited by a limiting pin 18. The limiting seat 11 is fixed to the movable seat 16. Multiple adjusting plates 2 13 are provided and slide along the sliding groove 1101 of the limiting seat 11 via the slide 12. The screw 14 is fixed to the bottom of the slide 12 and inserted into the sliding groove 1601 of the movable seat 16. The nut 15 is rotatably mounted on the screw 14 to limit the downward movement of the screw 14. The bracket 3 8 is fixed to the edge of the limiting seat 11. Multiple adjusting plates 1 9 are provided through the upper end of the bracket 3 8 and limited by a locking pin 17 that rotates on the bracket 3 8. The limiting head 10 is slidably mounted at the end of the adjusting plate 1 9.

[0024] This device uses a vertically placed metal bellows, which can directly flush out debris and impurities during cleaning. The bottom of the metal bellows is not affected by the device's components, thus avoiding incomplete cleaning and the problem of water not draining easily from the bottom of the metal bellows. Furthermore, the device provides stable confinement to the metal bellows, making cleaning more convenient.

[0025] A convex key is provided on one side of the outer wall of the drive rod 3, and a concave key is provided on the inner wall of the toothed ring 4. The outer wall contour of the drive rod 3 is adapted to the inner wall contour of the toothed ring 4; thus, the drive rod 3 can move downward and rotate at the same time, thereby driving the cleaning brush 7 to clean the metal bellows from top to bottom.

[0026] The limiting head 10 has an arc-shaped structure, with a protrusion on one end face and a groove on the other end face. The adjusting plate 9 is inserted into the groove, and a fixing post is also provided in the groove, penetrating the adjusting plate 9.

[0027] The thickness of the adjusting plate 9 is less than the width of the groove so that the position of the limiting head 10 can be adjusted up and down along the adjusting plate 9. The limiting head 10 can move up and down at the end of the adjusting plate 9 so that the protrusion of the limiting head 10 can be embedded in the groove of the outer wall of the metal bellows. Then, the locking pin 17 is rotated to lock the adjusting plate 9 on the bracket 8.

[0028] The limiting seat 11 is a hollow, inverted frustum-shaped structure with openings at both ends; this is to accommodate and limit metal bellows of different sizes, prevent the bottom of the metal bellows from moving, and allow water for cleaning the metal bellows to flow out from the bottom of the moving seat 16, preventing water accumulation and affecting the normal cleaning of the lower end of the metal bellows.

[0029] A limiting pin 18 is also inserted into the base 1 to restrict the movement of the limiting seat 11; after the moving seat 16 is pushed directly below the cleaning brush 7, the limiting pin 18 can be inserted into the corresponding position on the base 1, thereby limiting the moving seat 16 and preventing the moving seat 16 from moving on the base 1 when cleaning the metal bellows.

[0030] Working principle: The water outlet connected to the external water source is installed on the bottom surface of the upper end plate of bracket 101.

[0031] Positioned above the cleaning brush 7, with its outlet facing downwards towards the cleaning brush 7, the height of the adjusting plate 13 is adjusted beforehand according to the size of the metal bellows by sliding the slide block 12. The nut 15 is rotated until it fits against the surface of the limiting seat 11, restricting the downward movement of the adjusting plate 13. The metal bellows is then placed on the inner wall of the limiting seat 11.

[0032] Section plate 2 13 supports the bottom of the metal bellows. It can pull the horizontal adjustment plate 2 13 to support the bottom of the metal bellows while pulling the adjustment plate 2 13 out of the bottom of the metal bellows as much as possible to facilitate subsequent cleaning of the inner wall of the metal bellows.

[0033] At this time, push the adjusting plate 9 and make slight up-down adjustments to the limiting head 10 so that the protrusion in the middle of the limiting head 10 is embedded in the groove on the outer wall of the metal bellows. Then rotate the locking pin 17 to lock the adjusting plate 9 on the bracket 8, thus limiting the metal bellows. Push the metal bellows to the position directly below the cleaning brush 7 and insert the limiting pin 18 into the corresponding position on the base 1 to restrict the movement of the moving seat 16.

[0034] At this time, the external water source is connected, the electric push rod 2 is driven to push the drive rod 3 to move downward, and at the same time the motor 6 drives the gear 5 to rotate. The gear 5 drives the gear ring 4 to rotate synchronously, and then the gear ring 4 can drive the drive rod 3 to rotate. The drive rod 3 can then drive the cleaning brush 7 to rotate. The cleaning brush 7 enters the inside of the metal bellows, thereby cleaning the inside of the metal bellows.

[0035] After cleaning, the movable seat 16 can be pulled out from the bracket 101 to remove the metal bellows.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
